I am working on a model transformation like KM32Problem. This transformation instantiate a problem model to check the input model and to generate error.

The source meta-model is the Ecore of UML2.3 and the target one is problem.ecore.

The ATL file is correct (tested with a run configurations).
But here is my problem : i want to automate the transformation in order to check the input model. So i decided to create a new ATL plugin with the wizard. I have chosen "ATL launched configuration" to generate the plugin.

The problem is that the plugin doesn't find the file problem.ecore during the runtime. I tried to move the file in the package .files of the plugin (with the Uml2problem.java generated), I tried to change the Uml2problem.metatmodels.Problem path...But nothing...

For those who got the same problem, here is some elements of response :
the path of the metamodel, in the properties file, has to be like this (from src): Uml2problem.metamodels.Problem = src/uml2problem/files/problem.ecore

With this path, the error disappears. Nevertheless, the path is not correct when the ATL plugin is integrated in an Eclipse Solution.
Perhaps a path like platform:/resource/project-name/path or platform:/plugin/plugin-id/path but I didn't find the right path.

Path for the properties file :
If the ATL Plugin is used alone : src/uml2problem/files/problem.ecore
If the ATL Plugin is integrated in an Eclipse Plugin : platform:/plugin/plugin-id/src/uml2problem/files/problem.ecore
